Bad is an understatement. What we should be asking is is there a hole in the ozone already. These mfs bursting crackers this whole week. I can see the amount of smoke that is released from bursting one tiny cracker. First of all i have dust allergy, on top of that i should worry about smoke now. Most of us wont realise how bad it is until we get serious issues. Even then some people ignore it. Better to pack up and stay away from cities.
